16. Examine the ethical considerations in deploying sentiment analysis models, particularly in social media. How can biases be addressed in such applications?

Ethical considerations in sentiment analysis involve addressing biases present in training data, as social media data may reflect societal biases. Solutions include diverse dataset collection, bias detection algorithms, and transparent model development.

Ethical considerations in sentiment analysis are irrelevant, as biases are inherent in language and cannot be mitigated.

Addressing biases in sentiment analysis is unnecessary, as users are aware of potential biases in social media content.

Biases in sentiment analysis models cannot be addressed, and deploying biased models is acceptable.

17. Compare and contrast the bag-of-words model and word embeddings in NLP. Highlight their respective advantages and limitations.

The bag-of-words model represents text as an unordered set of words, ignoring word order and context. Word embeddings capture semantic relationships between words and consider context. Bag-of-words is simpler but lacks context, while word embeddings are more nuanced.

Both the bag-of-words model and word embeddings are identical in their representation of textual information.

The bag-of-words model is superior to word embeddings in capturing contextual information. Word embeddings are limited to specific tasks.

Word embeddings and the bag-of-words model are interchangeable and have no distinct advantages or limitations.

It evaluates syntactic complexity

It optimizes language models

It translates text between languages

It resolves ambiguity by determining the meaning of a word based on context

19. Define 'corpus' in NLP and its role in training language models.

It optimizes language models

It evaluates syntactic complexity

It translates text between languages

It refers to a collection of texts used to train and test language models

20. What does TF-IDF stand for in the context of document representation?

Term Frequency-Inverse Document Frequency

Total Frequency-Indexed Document Format

Text Feature-Integrated Data Filter

Tokenized Format-Inverted Document Filter

21. What is the purpose of stemming in NLP?

Identifying named entities

Reducing words to their base or root form

Point of Sale

Part of Speech

Power of Syntax

Pattern of Semantics

25. Explain the role of attention mechanisms in advanced Natural Language Processing models and provide an example of their application.

Attention mechanisms enable models to focus on important parts of the input sequence, improving performance. An example is in machine translation, where the model pays attention to specific words during the translation process.

Attention mechanisms are irrelevant in NLP models and do not contribute to performance improvement.

Attention mechanisms are limited to image processing tasks and are not applicable in NLP.

Attention mechanisms focus on random parts of the input sequence, making them unreliable for NLP applications.

Cross-lingual NLP faces challenges due to language variations. Techniques include parallel corpora alignment, machine translation, and transfer learning across languages to overcome language barriers.

Cross-lingual NLP is inherently easy, and language barriers do not pose significant challenges.

Challenges in cross-lingual NLP are unsolvable, and language variations are insurmountable barriers.

Cross-lingual NLP challenges only arise in spoken language tasks and not in written text analysis.

30. In the context of neural networks, explain the concept of transfer learning and its application in Natural Language Processing.

Transfer learning involves training a model on a specific NLP task and transferring the learned knowledge to unrelated tasks.

Transfer learning leverages pre-trained models on large datasets and fine-tunes them for specific NLP tasks, reducing the need for extensive training.

Transfer learning focuses on transferring linguistic rules between different languages to enhance NLP performance.

Transfer learning is not applicable in Natural Language Processing tasks.
